Answer:
The speed is 900,000,000 km/h
Step-by-step explanation:
The ratio of distance covered to time taken gives the speed of an object
[tex]Speed, \ v = \dfrac{Distance, \ d}{Time, \ t}[/tex]
Given that the distance covered, d = 5 × 10⁵ cm
The time to travel the given distance, t = 2 × 10⁻⁵ seconds
Therefore;
[tex]Speed, \ v = \dfrac{5 \times 10^{5} \ cm}{2 \times 10^{-5} \ s} = 2.5 \times 10 ^{10} \ cm/s[/tex]
In km/h, we have;
1 cm = 0.00001 km
∴ v = 2.5 × 10¹⁰ cm/s × 1 km/(100,000 cm) × 3,600 s/h = 900,000,000 km/h
The speed is 2.5 × 10¹⁰ cm/s or 900,000,000 km/h.

NO LINKS ACCEPTED -The robot factory is a learning center where children can build robots. The project fee per visit is $15 and each hour of time (x) at the factory costs $4. Jesse goes to the robot factory one afternoon and was charged $40 for the visit. Write an equation that models this situation where X is the number of hours Jesse stands at the robot factory
Answers
Answer:
15 + 4x = 40
Step-by-step explanation:
To construct this equation, we'll list all the values we will include first.
The total fee equals $40, so we'll put 40 on one side of the equation.
On the other side, we have to put the values that make up the total. The fee is made with the project cost plus the hourly rate. The first part of this is the beginning cost, $15. Added to this is the hourly cost, $4, times the number of hours spent. So, the other side of the equation is 15 (the starting cost) plus 4 (the rate) times x (the unknown number of hours).
So, our equation is 15 + 4x = 40.
Good luck ^^

Answer:
144cm^3
Step-by-step explanation:
1) split the figure so you can find the volume of two rectangular prisms.
2) Find the volume of the first rectangular prism with the measurements of 2, 5, and 8. So the volume is 80
3) Find the volume of the second rectangular prism with the measurements of 4, 2, and 8. So you have 64
4) Add the two values 80+64.
5) Then that's your answer; 144

Thirty students in an art class each receive an identical set of 20 markers. As part of a project, each student is asked to close their eyes and select from his or her set at random. You developed a model that predicts the probability of a student randomly picking a yellow marker is 0.1. Which result would most likely cast doubt on your model? (Hint: what is the theoretical probability of 30 students choosing a yellow marker each from a pack of 20 markers.)
10 student pick red markers.
10 student pick yellow markers.
2 student pick blue markers.
2 student pick yellow markers.
3 students pick yellow markers.
3 students pick green markers.
Answers
okay 1 student = 1/20 chance of picking yellow
1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets
30/600 = 0.05 = 5% chance of choosing yellow.
I each studnet picks 1 yellow marker. Is that all the options?

Stanley needs 31 feet and 2 inches of fencing.
Step-by-step explanation:
In order to answer this problem, you need to find the perimeter of the dog run.
Since: [tex]P=2(l+w)[/tex]
and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches
Plug in what we know :
[tex]P=2(149+56)[/tex]
and solve:
[tex]P=410[/tex] inches
The dog run has a perimeter of 410 inches.
However, now we need to subtract 36 inches since the gate doesn't need fencing.
[tex]410-36=374[/tex] inches.
The dog run needs 374 inches of fencing.
In order to find out how many feet of fencing that is, divide it by 12.
[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.
Answer:
31 feet and 2 inches of fencing :))<3

Out of Koley's 15 plants, 6 were carrots. What percentage of plants are carrots?
**And don’t even bother putting a link...
Answers
Answer:
40%
Step-by-step explanation:
➡6/15×100
➡600/15
➡40%
Answer: 40% of the plants are carrots
Step-by-step explanation:
In order to figure out the percentage, we have to find what "part" of the "total" are the carrots, which is given. We already know that 6 of the total 15 plants are carrots. When referring to a percentage, basically we are trying to find out how many carrots there would be, if we were to have 100 plants. So, in order to do so, we would need 100 plants. I'll make it even more simple:
We have 15 plants - 6 of which are carrots
If we were to have
100 plants - HOW MANY would be carrots??
The answer to our question is also the percentage we are looking for. If we replace HOW MANY with x, than we would have this equation: 15*x=6*100, so 15x=600 and x=40, so the percentage is 40%.
In order to make this easier, as i said in the beginning we are referring to the part of a total, with given numbers, so if we would divide 6 out of 15, we would have 6/15=0.4 , multiplying that number with 100 (for the percentage), you get 40% again, with a faster and easier way. Practice makes perfect.

Answers
Answer:
The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.
Step-by-step explanation:
The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.
In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.
